Bomb targeted Iraq oil row auditor

BAGHDAD, Iraq (CNN) -- The Iraqi official in charge of investigating allegations against the U.N. oil-for-food program was the target of the bomb that killed him, according to the interior ministry.

The investigation shows Ihsan Kareem, president of the Finance Ministry's audit board, was deliberately killed by an improvised explosive device attached to the underside of his car, the spokesman said without elaborating.

Kareem died the day after the explosion in early July.

His driver also died, and three other people were wounded by the blast outside Baghdad's Yarmuk hospital.

The Board of Supreme Audit has been investigating allegations that the ousted regime of Saddam Hussein siphoned billions from the oil-for-food program.

Under it, Iraq was allowed to sell limited amounts of oil to ease the burden on the public despite U.N. sanctions imposed after Saddam invaded Kuwait in 1990.
